On the terms and conditions set forth in this Agreement, each Lender severally agrees to lend to the Borrower, from time to time during the Revolving Credit Period, amounts not to exceed in the aggregate at any one time outstanding (together with its LC Exposure) the amount of such Lender’s Commitment. Each Borrowing under this Section 2.01 shall be in an aggregate principal amount of $15,000,000 or any larger multiple of $1,000,000 (except that any such Borrowing may be in the aggregate amount of the unused Commitments or any lesser aggregate amount required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.17(e)) and shall be made from the several Lenders ratably in proportion to their respective Commitments. Within the foregoing limits, the Borrower may borrow under this Section, repay, or to the extent permitted by Section 2.12, prepay Loans and reborrow at any time during the Revolving Credit Period under this Section. Failure by any Lender to make Loans as required under the terms of this Agreement will not relieve any other Lender of its obligations hereunder. Notwithstanding the foregoing, any Money Market Loans made by a Lender shall be deemed Usage of the total Commitments for the purpose of availability, but shall not reduce such Lender’s obligation to lend its pro rata share of the total Commitments.

(d) Submission and Contents of Money Market Quotes. (i) Each Lender may submit a Money Market Quote containing an offer or offers to make Money Market Loans in response to any Invitation for Money Market Quotes. Each Money Market Quote must comply with the requirements of this Section 2.03(d) and must be submitted to the Agent by facsimile transmission at its offices specified in or pursuant to Section 9.01 not later than (x) 9:30 A.M. (New York City time) on the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction, or (y) 9:30 A.M. (New York City time) on the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Agent shall have mutually agreed and shall have notified to the Lenders not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective); provided that Money Market Quotes submitted by the Agent (or any Affiliate of the Agent) in the capacity of a Lender may be submitted, and may only be submitted, if the Agent or such Affiliate notifies the Borrower of the terms of the offer or offers contained therein not later than (x) 9:15 A.M. (New York City time) on the third Euro-Dollar Business Day prior to the proposed

(e) Notice to Borrower. The Agent shall promptly notify the Borrower of the terms (x) of any Money Market Quote submitted by a Lender that is in accordance with Section 2.03(d) and (y) of any Money Market Quote that amends, modifies or is otherwise inconsistent with a previous Money Market Quote submitted by such Lender with respect to the same Money Market Quote Request. Any such subsequent Money Market Quote shall be disregarded by the Agent unless such subsequent Money Market Quote is submitted solely to correct a manifest error in such former Money Market Quote. The Agent’s notice to the Borrower shall specify (A) the aggregate principal amount of Money Market Loans for which offers have been received for each Interest Period specified in the related Money Market Quote Request, (B) the respective principal amounts and Money Market Margins or Money Market Absolute Rates, as the case may be, so offered (including the names of the Lenders) and (C) if applicable, limitations on the aggregate principal amount of Money Market Loans for which offers in any single Money Market Quote for any Interest Period may be accepted.

(f) Acceptance and Notice by Borrower. Not later than 10:30 A.M. (New York City time) on (x) the third Euro-Dollar Business Day prior to the proposed date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in either case, such other time or date as the Borrower and the Agent shall have mutually agreed upon and shall have notified to the Lenders not later than the date of the Money Market Quote Request for the first LIBOR Auction or Absolute Rate Auction for which such change is to be effective), the Borrower shall notify the Agent of its acceptance or non-acceptance of the offers so notified to it pursuant to Section 2.03(e). In the case of acceptance, such notice (a “Notice of Money Market Borrowing”) shall specify the aggregate principal amount of offers for each Interest Period that are accepted. The Borrower may accept any Money Market Quote for any Interest Period in whole or in part; provided that:

(c) Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Agent such Lender’s share of such Borrowing, the Agent may assume that such Lender has made such share available to the Agent on the date of such Borrowing in accordance with Section 2.04(b) and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such share available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.09 and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Loan included in such Borrowing for purposes of this Agreement.

(c) The Borrower may, by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders) not less than 45 days and not more than 90 days prior to any anniversary of the date hereof, request that the Lenders extend the Maturity Date and the Commitments for an additional period of one year (the date of any such request being called the “Request Date”). Each Lender shall, by notice to the Borrower and the Agent given not later than the 20th day after the date of the Agent’s receipt of the Borrower’s extension request, advise the Borrower whether or not it agrees to the requested extension (each Lender agreeing to a requested extension being called a “Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender that has not so advised the Borrower and the Agent by such day shall be deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to an extension request, then the Maturity Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Maturity Date theretofore in effect. The decision to agree or withhold agreement to any Maturity Date extension shall be at the sole

discretion of each Lender. The Commitment of any Declining Lender shall terminate on the Maturity Date in effect immediately prior to giving effect to any such extension (such Maturity Date being called the “Existing Maturity Date”). The principal amount of any outstanding Loans made by Declining Lenders, together with any accrued interest thereon and any accrued fees and other amounts payable to or for the accounts of such Declining Lenders hereunder, shall be due and payable on the Existing Maturity Date, and on the Existing Maturity Date, the Borrower shall also make such other prepayments of its Loans as shall be required in order that, after giving effect to the termination of the Commitments of, and all payments to, Declining Lenders pursuant to this sentence, the sum of the aggregate outstanding principal amount of the Loans plus the LC Exposure shall not exceed the aggregate amount of the Commitments that shall have been extended beyond the Existing Maturity Date. Notwithstanding the foregoing provisions of this Section, the Borrower shall have the right, pursuant to Section 8.06, at any time prior to the Existing Maturity Date, to replace a Declining Lender with one or more Lenders or other financial institutions that will agree to a request for the extension of the Maturity Date, and any such replacement Lender shall for all purposes constitute a Consenting Lender. Notwithstanding the foregoing, no extension of the Maturity Date pursuant to this Section shall become effective unless (i) on or prior to the anniversary of the date hereof that immediately follows the Request Date (such date, the “Extension Date”), the Agent shall have received documents consistent with those delivered with respect to the Borrower under Subsections (b), (c) and (d) of Section 3.01, giving effect to such extension and (ii) on the Extension Date the condition set forth in Section 3.01(e) shall be satisfied (with all references in such Section to the Effective Date being deemed to be references to the Extension Date; provided, however, that, solely for purposes of this sentence, the date in Section 4.04(b) shall be deemed to be December 31 of the year for which the Borrower shall most recently have filed an Annual Report on Form 10-K with the Securities and Exchange Commission prior to the Request Date, and provided further, that solely for purposes of this sentence, clause (b) of the definition of “Disclosure Documents” shall be deemed to refer to the Borrower’s most recently filed Annual Report on Form 10-K prior to the Request Date, clause (c) of such definition shall be deemed to refer to the Borrower’s Quarterly Reports on Form 10-Q filed for all the quarterly periods, if any, beginning on or after the end of the annual period covered by said Annual Report and ending on or before the Request Date, and clause (d) of such definition shall be deemed to refer to the Borrower’s Current Reports on Form 8-K, if any, filed or furnished prior to the Request Date).

SECTION 2.08. Increase in Commitments. (a) During the Revolving Credit Period, the Borrower may on one or more occasions, by written notice to the Agent (which shall promptly deliver a copy to each of the Lenders), executed by the Borrower and one or more financial institutions (any such financial institution referred to in this Section being called an “Augmenting Lender”), which may include any Lender, cause Commitments to be made available by the Augmenting Lenders (or cause the Commitments of the Augmenting Lenders to be increased, as the case may be) in an amount for each Augmenting Lender set forth in such notice; provided that (i) the aggregate amount of all such increases pursuant to this Section shall not exceed $350,000,000, (ii) each Augmenting Lender, if not already a Lender hereunder, shall be subject to the approval of the Agent (which approval shall not be unreasonably withheld) and (iii) each Augmenting Lender, if not already a Lender hereunder, shall become a party to this Agreement by completing and delivering to the Agent a duly executed accession agreement in a form satisfactory to the Agent and the Borrower. Any such notice shall set forth the amount of the requested increase in the total Commitments (which shall be the lesser of (x) a minimum aggregate amount of $20,000,0000 or any larger multiple of $5,000,000 or (y) the remaining aggregate allowance for such increases) and the date on which such increase is requested to become effective. Increases and new Commitments created pursuant to this Section 2.08(a) shall become effective on the date specified in the notice delivered by the Borrower pursuant to the first sentence of this Section 2.08(a). Notwithstanding the foregoing, no increase in the total Commitments (or in the Commitment of any Lender) shall become effective under this Section 2.08(a) unless, (i) on the date of such increase, the conditions set forth in Sections 3.02(b) and 3.02(d) (without giving effect to the parenthetical in Section 3.02(d)) shall be satisfied (as though a Borrowing were being made on such date) and the Agent shall have received a certificate to that effect dated such date and executed by a Responsible Financial Officer of the Borrower, and (ii) the Agent shall have received (to the extent requested by the Agent reasonably in advance of such date) documents consistent with those delivered under Sections 3.01(c) and 3.01(d) as to the corporate power and authority of the Borrower to borrow hereunder and as to the enforceability of this Agreement after giving effect to such increase.

The “London Interbank Offered Rate” applicable to any Interest Period means the rate per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) appearing on the Moneyline Telerate Screen page 3750 (or any successor page) as the London interbank offered rate for deposits in Dollars at 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period for a period equal to such Interest Period; provided that, if for any reason such rate is not available, the term “London Interbank Offered Rate” applicable to any Interest Period shall mean the rate per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) appearing on Reuters Screen LIBO Page (or any successor page) as the London interbank offered rate for deposits in Dollars at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period for a period equal to such Interest Period; provided, however, if more than one rate is specified on Reuters Screen LIBO Page (or any successor page), the applicable rate shall be the arithmetic mean of all such rates.

(c) Any overdue principal of and, to the extent permitted by law, overdue interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 2% plus the Euro-Dollar Margin plus the higher of (i) the London Interbank Offered Rate applicable to such Loan and (ii) the average (rounded upward, if necessary, to the next higher 1/100 of 1%) of the respective rates per annum at which one day (or, if such amount due remains unpaid more than three Euro-Dollar Business Days, then for such other period of time not longer than three months as the Agent may select) deposits in dollars in an amount approximately equal to such overdue payment due to the Agent are offered to the Agent in the London interbank market for the applicable period determined as provided above (or, if the circumstances described in Section 8.01 shall exist, at a rate per annum equal to the sum of 2% plus the Base Rate for such day).

(d) Subject to clause (y) of Section 8.01, each Money Market LIBOR Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the sum of the London Interbank Offered Rate for such Interest Period plus (or minus) the Money Market Margin quoted by the Lender making such Loan in accordance with Section 2.03. Each Money Market Absolute Rate Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the Money Market Absolute Rate quoted by the Lender making such Loan in accordance with Section 2.03. Such interest shall be payable for each Interest Period on the earlier of (i) the last day thereof, (ii) three months after the initial date thereof and, if such Interest Period is longer than three months, at intervals of three months thereafter or (iii) the Maturity Date. Any overdue principal of and, to the extent permitted by law, overdue interest on any Money Market Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 2% plus the Base Rate for such day.

(e) The Agent shall determine (in accordance with this Agreement) each interest rate applicable to the Loans hereunder. The Agent shall give prompt notice to the Borrower by facsimile transmission and the participating Lenders by facsimile transmission of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error.

SECTION 2.10. Fees. (a) Facility Fee. The Borrower shall pay to the Agent for the account of the Lenders, ratably in proportion to their Commitments (or, if the Commitments have terminated, ratably in proportion to their outstanding Loans and LC Exposure), a facility fee at the rate of (i) 0.050% per annum during each Level I Period, (ii) 0.060% per annum during each Level II Period, (iii) 0.070% per annum during each Level III Period, (iv) 0.080% per annum during each Level IV Period, (v) 0.100% per annum during each Level V Period, (vi) 0.125% per annum during each Level VI Period and (vii) 0.175% per annum during each Level VII Period. Such facility fee shall accrue (i) from and including the Effective Date to but excluding the last day of the Revolving Credit Period, in each case, on the daily average aggregate amount of the Commitments (whether used or unused) and (ii) if any Loan or LC Exposure remains outstanding after the Revolving Credit Period (or if any Loan or LC Exposure of any Lender remains outstanding after such Lender’s Commitment shall have terminated), from and including the last day of the Revolving Credit Period (or the termination of such Commitment) to but excluding the date such Loans shall be repaid in full, on the daily average aggregate outstanding principal amount of such Loans and LC Exposure.

(b) Letter of Credit and Fronting Fees. The Borrower agrees to pay (i) to the Agent for the account of each Lender a letter of credit fee with respect to its participations in Letters of Credit, which shall accrue at the Euro-Dollar Margin used to determine the interest rate applicable to Euro-Dollar Loans (and solely for purposes of determining the applicable Euro-Dollar Margin used in computing Letter of Credit participation fees Usage shall be deemed to be greater than 50%) on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to each Issuing Bank a fronting fee, which shall accrue at the rate or rates per annum separately agreed upon between the Borrower and the applicable Issuing Bank on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) attributable to Letters of Credit issued by such Issuing Bank during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as such Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit by such Issuing Bank or the processing of drawings thereunder.

(c) Payments. Except as otherwise indicated, accrued facility fees, letter of credit fees and fronting fees under this Section 2.10 shall be payable quarterly in arrears on (i) each Quarterly Date, (ii) the Maturity Date and (iii) if any Loans or LC Exposure remains outstanding after the Revolving Credit Period, the date such Loans shall be repaid in full and such LC Exposure ceases to exist. Any other fees payable to any Issuing Bank pursuant to this Section shall be payable within 10 days after demand.

SECTION 2.11. Method of Electing Interest Rates. (a) The Loans included in each Committed Borrowing shall bear interest initially at the type of rate specified by the Borrower in the applicable Notice of Committed Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the provisions of Article VIII), as follows:

(i) if such Loans are Base Rate Loans, the Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and

(ii) if such Loans are Euro-Dollar Loans, the Borrower may (x) elect to convert such Euro-Dollar Loans to Base Rate Loans as of any Domestic Business Day, (y) elect to convert such Euro-Dollar Loans to Euro-Dollar Loans with an Interest Period different from the then current Interest Period applicable to such Loans as of any Euro-Dollar Business Day or (z) elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period beginning on the last day of the then current Interest Period applicable to such Loans;

provided that, if the Borrower elects to convert any Euro-Dollar Loans to Base Rate Loans or to Euro-Dollar Loans with a different Interest Period, as of any day other than the last day of the then current Interest Period applicable to such Loans, the Borrower shall reimburse each Lender in accordance with Section 2.14.

Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the Agent (i) at least one Domestic Business Day before such notice is to be effective if the relevant Loans are to be converted into Base Rate Loans or (ii) at least three Euro-Dollar Business Days before such conversion or continuation is to be effective if such Loans are to be converted into, or continued as, Euro-Dollar Loans.

A Notice of Interest Rate Election may, if it so specifies, apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such Notice applies, and the remaining portion to which it does not apply, are each $15,000,000 or any larger multiple of $1,000,000.

(b) Each Notice of Interest Rate Election shall specify:

(i) the Group of Loans (or portion thereof) to which such notice applies;

(ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of Section 2.11(a);

(iii) whether such Group of Loans (or portion thereof) is to be converted to Base Rate Loans or Euro-Dollar Loans or continued as Euro-Dollar Loans for an additional Interest Period; and

(iv) if such Loans (or portions thereof) are to be converted to or continued as Euro-Dollar Loans, the duration of the Interest Period to be applicable thereto immediately after such conversion or continuation.

Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period.

(c) Upon receipt of a Notice of Interest Rate Election from the Borrower pursuant to Section 2.11(a), the Agent shall promptly notify each Lender of the contents thereof and such notice shall not thereafter be revocable by the Borrower. If the Borrower fails to deliver a timely Notice of Interest Rate Election to the Agent for any Euro-Dollar Loans, such Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto.

SECTION 2.12. Prepayments. (a) The Borrower may (i) upon notice to the Agent to be received no later than 10:30 A.M. (New York City time), prepay the Base Rate Loans (or any Money Market LIBOR Loans which bear interest at the Base Rate at such time for the reason stated in Section 8.01), in whole or in part, on any Domestic Business Day and (ii) upon at least two Euro-Dollar Business Days’ notice to the Agent, prepay any Euro-Dollar Loan, in whole or in part, in amounts aggregating $15,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment; provided that a Money Market Loan may not be prepaid without the prior written consent of the Lender that holds such Money Market Loan, other than as contemplated by clause (i) above. Each such optional prepayment shall be applied to prepay ratably the relevant Loans of the several Lenders. Prepayment of a Euro-Dollar Loan on any day other than the last day of an Interest Period applicable thereto shall be subject to Section 2.14.

SECTION 2.13. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on, the Loans, fees and reimbursements of LC Disbursements hereunder, not later than 12:00 Noon (New York City time) on the date when due, in Federal or other funds immediately available in New York City, to the Agent at its address referred to in its Administrative Questionnaire (or to an Issuing Bank, in the case of payments to be made directly to an Issuing Bank as expressly provided herein), without set-off or counterclaim. The Agent will promptly distribute to each Lender its ratable share of each such payment received by the Agent for the account of the Lenders, or to each applicable Issuing Bank in the case of payments for the account of one or more of the Issuing Banks. Whenever any payment of principal of, or interest on, any Base Rate Loans or fees shall be due on a day which is not a Domestic Business Day, the datefor payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever anypayment of principal of, or interest on, the Euro-Dollar Loans and Money Market LIBOR Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month or falls after the Maturity Date, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. Whenever any payment of principal of, or interest on, the Money Market Absolute Rate Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time.

(b) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders or one or more Issuing Banks hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender or each applicable Issuing Bank, as the case may be, on such due date an amount equal to the amount then due such Lender or such Issuing Bank. If and to the extent that the Borrower shall not have so made such payment, each Lender or each applicable Issuing Bank, as the case may be, shall repay to the Agent forthwith on demand such amount distributed to such Lender or such Issuing Bank together with interest thereon, for each day from the date such amount is distributed to such Lender or such Issuing Bank until the date such Lender or such Issuing Bank repays such amount to the Agent, at the Federal Funds Rate.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 2.13(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary (as to which the provisions of this Section 2.13(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

SECTION 2.14. Funding Losses. If the Borrower makes any payment of principal with respect to any Fixed Rate Loan or any Fixed Rate Loan is converted to a Base Rate Loan (pursuant to Section 2.11, Section 2.12, Article VI or Article VIII) on any day other than the last day of an Interest Period applicable thereto or the end of an applicable period fixed pursuant to Section 2.09(c), or if any Lender assigns any Fixed Rate Loan as required by Section 8.06 on any day other than the last day of an Interest Period applicable thereto, or if the Borrower fails to borrow or prepay any Fixed Rate Loan after notice has been given to any Lender in accordance with Section 2.04(a) or Section 2.12, the Borrower shall reimburse each Lender within 15 days after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss reasonably incurred in obtaining, liquidating or employing deposits from third parties, but excluding loss of margin for the period after such payment or conversion or assignment or failure to borrow or prepay; provided that such Lender shall have delivered to the Borrower a certificate as to the amount of such loss or expense with an explanation of the calculation of such loss or expense, which certificate shall be conclusive if made reasonably and in good faith.

SECTION 2.16. Regulation D Compensation. For each day for which a Lender is required to maintain reserves in respect of either (x) “Eurocurrency Liabilities” (as defined in all regulations of the Board of Governors of the Federal Reserve System) or (y) any other category of liabilities which includes deposits by reference to which the interest rate in Euro-Dollar Loans is determined or any category of extensions of credit or other assets which includes loans by a non-United States office of any Lender to United States residents, such Lender may require the Borrower to pay, contemporaneously with each payment of interest on the Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such Lender at a rate per annum determined by such Lender up to but not exceeding the excess of (i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Agent, in which case such additional interest on the Euro-Dollar Loans of such Lender shall be payable to such Lender at the place indicated in such notice with respect to each Interest Period commencing at least five Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least five Euro-Dollar Business Days prior to each date on which interest is payable on the Euro-Dollar Loans of the amount then due to such Lender under this Section. Such Lender’s notice to the Borrower shall set forth its calculation of such additional interest and such calculation shall be conclusive if made reasonably and in good faith.

SECTION 2.17. Letters of Credit. (a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit denominated in Dollars for its own account in a form reasonably acceptable to the Agent and the applicable Issuing Bank, at any time and from time to time during the Revolving Credit Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. The parties hereto acknowledge and agree that (i) Letters of Credit may be issued to support obligations of Subsidiaries of the Borrower as well as the Borrower, (ii) Letters of Credit issued to support obligations of a Subsidiary may state that they are issued for such Subsidiary’s account and (iii) regardless of any such statement in any Letter of Credit, the Borrower is the “account party” in respect of all Letters of Credit and will be responsible for reimbursement of LC Disbursements as provided herein.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver (or transmit by electronic communication or facsimile transmission, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Domestic Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 2.17(c)), the amount of such Letter of Credit in Dollars, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the applicable Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (X) the Agent shall have confirmed, based solely on the information delivered to it pursuant to Section 2.17(k) below, that (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), (A) after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed $150,000,000, (ii) the amount of the LC Exposure attributable to Letters of Credit issued by the applicable Issuing Bank will not exceed the LC Commitment of such Issuing Bank and (iii) the sum of the total LC Exposure plus the aggregate outstanding principal amount of the Loans shall not exceed the aggregate amount of the Commitments, and (B) in the event the Maturity Date shall have been extended as provided in Section 2.06(c), the sum of the LC Exposure attributable to Letters of Credit expiring after any Existing Maturity Date and the aggregate principal amount of all Money Market Loans maturing after such Existing Maturity Date shall not exceed the aggregate Commitments that have been extended to a date after the latest expiration date of such Letters of Credit and

the latest maturity of such Money Market Loans, and (Y) the Issuing Bank shall not have received written notice from any Lender, the Agent or the Borrower, at least one Business Day prior to the requested date of issuance, amendment, renewal or extension of the applicable Letter of Credit, that one or more applicable conditions contained in Section 3.02 shall not be satisfied.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Domestic Business Days prior to the Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Agent, for the account of the applicable Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.17(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.17(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Agent an amount equal to such LC Disbursement not later than 12:00 Noon, New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 A.M., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 Noon, New York City time, on (i) the Domestic Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 A.M., New York City time, on the day of receipt, or (ii) the Domestic Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.02 that such payment be financed with a Base Rate Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Base Rate Borrowing. If the Borrower fails to make such payment when due, the Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.04 with respect to Loans made by such Lender (and Section 2.04 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Agent shall promptly pay to the applicable Issuing Bank the amounts so received by the Agent from the Lenders. For the avoidance of doubt, any Declining Lender that has been replaced by a Substitute Lender pursuant to Section 8.06 prior to the date of reimbursement shall not be required to make any payment to the Agent or the applicable Issuing Bank pursuant to the preceding sentence, regardless of whether the applicable Letter of Credit was issued before or after such Lender has become a Declining Lender. Promptly following receipt by the Agent of any payment from the Borrower pursuant to this Section 2.17(e), the Agent shall distribute such payment to the applicable Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.17(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.17(e) to reimburse any Issuing Bank for any LC Disbursement (other than the funding of Base Rate Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.17(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.17(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Agent, the Lenders nor the Issuing Banks (nor any of their Affiliates, directors, officers, employees, agents and advisors, or their Affiliates’ directors, officers, employees, agents and advisors), shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the applicable Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or wilful misconduct on the part of an Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the applicable Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Agent and the Borrower by telephone (confirmed by facsimile transmission) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(i) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Domestic Business Day that the Borrower receives notice from the Agent or the Required Lenders that the Required Lenders are demanding the deposit of cash collateral pursuant to this Section 2.17(i), the Borrower shall deposit in an account with the Agent, in the name of the Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in Section 6.01(g) or Section 6.01(h). Such deposit shall be held by the Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Agent to reimburse each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the Required Lenders), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Domestic Business Days after all Events of Default have been cured or waived.

(k) Issuing Bank Reports. Unless otherwise agreed by the Agent, each Issuing Bank shall report in writing to the Agent (i) on or prior to each Business Day on which such Issuing Bank issues, amends, renews or extends any Letter of Credit, the date of such issuance, amendment, renewal or extension and the aggregate face amount of the Letter of Credit issued, amended, renewed, or extended by it and outstanding after giving effect to such issuance, amendment, renewal or extension (and whether the amount thereof has changed), it being understood that such Issuing Bank shall not effect any issuance, renewal, extension or amendment resulting in an increase in the amount of any Letter of Credit without first obtaining written confirmation from the Agent that such increase complies with the conditions contained in clauses (A) and (B) of Section 2.17(b), (ii) on each Business Day on which such Issuing Bank makes an LC Disbursement, the date and amount of such LC Disbursement, (iii) on any Business Day on which the Borrower reimburses or fails to reimburse an LC Disbursement required to be reimbursed to such Issuing Bank on such day, the date of such reimbursement or failure and the amount of such LC Disbursement and (iv) on any other Business Day, such other information as the Agent shall reasonably request as to the Letters of Credit issued by such Issuing Bank and outstanding on such Business Day.

SECTION 5.07. Compliance with Laws. The Borrower will comply, and will cause its Consolidated Subsidiaries to comply, in all material respects with all applicable laws, except where any failure to comply therewith would not individually or collectively have a material adverse effect on the Borrower’s ability to perform its obligations hereunder, and except where necessity of compliance therewith is being contested in good faith by appropriate proceedings; provided, however, that with respect to compliance with ERISA, this Section 5.07 applies to the Borrower and its Consolidated Subsidiaries only in their respective capacities as employers and not in any other capacity (such as a fiduciary or service provider to Plans for the benefit of employers of others).

SECTION 5.08. Inspection of Property, Books and Records. The Borrower will keep proper books of record and account in which full, true and correct entries (in all material respects) in conformity with GAAP shall be made of all dealings and transactions in relation to its business and activities. The Borrower will permit representatives of any Lender at such Lender’s expense to visit and inspect the Borrower’s financial records and properties, to examine and make extracts from its books and records and to discuss its affairs and financial condition with the Borrower’s officers and (with the participation of or prior notice to such officers) independent public accountants, all at such reasonable times and as often as reasonably requested.

SECTION 5.09. Payment of Obligations. The Borrower will, and will cause each of its Consolidated Subsidiaries to, pay its tax liabilities and other material obligations, before the same shall become delinquent or in default, except where (a) (i) the validity or amount thereof is being contested in good faith by appropriate proceedings and (ii) the Borrower or such Consolidated Subsidiary has set aside on its books adequate reserves with respect thereto in accordance with GAAP or (b) the failure to make such payments could not reasonably be expected to have a material adverse effect on the Borrower’s ability to perform its obligations hereunder or on the financial condition of the Borrower and its Consolidated Subsidiaries, taken as a whole.

ARTICLE VIII

Change in Circumstances

SECTION 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar Loan or Money Market LIBOR Loan the Agent determines (which determination shall be conclusive absent manifest error) that deposits in dollars (in the applicable amounts) are not generally available in the London interbank market for such period or that the London Interbank Offered Rate cannot be determined in accordance with the definition thereof, the Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Lenders to make Euro-Dollar Loans, to convert outstanding Base Rate Loans into Euro-Dollar Loans or to convert outstanding Euro-Dollar Loans into Euro-Dollar Loans with a different Interest Period shall be suspended, (ii) each outstanding Euro-Dollar Loan or Money Market LIBOR Loan, as the case may be, shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto, and (iii) unless the Borrower notifies the Agent at least two Domestic Business Days before the date of any Euro-Dollar Borrowing or Money Market LIBOR Borrowing, as the case may be, for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, (x) if such Borrowing is a Euro-Dollar Borrowing, such Borrowing shall instead be made as a Base Rate Borrowing and (y) if such Borrowing is a Money Market LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall bear interest for each day from and including the first day to but excluding the last day of the Interest Period applicable thereto at the Base Rate for such day.

SECTION 8.02. Illegality. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Lender (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Lender shall so notify the Agent, the Agent shall forthwith give notice thereof to the other Lenders and the Borrower, whereupon until such Lender notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Euro-Dollar Loans, or to convert outstanding Base Rate Loans into Euro-Dollar Loans, or to convert outstanding Euro-Dollar Loans into Euro-Dollar Loans with a different Interest Period shall be suspended. Before giving any notice to the Agent pursuant to this Section 8.02, such Lender shall designate a different Applicable Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. If such notice is given, all Euro-Dollar Loans of such Lender then outstanding shall be converted to Base Rate Loans either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loans if such Lender may lawfully continue to maintain and fund such Loans to such day or (b) immediately if such Lender may not lawfully continue to maintain and fund such Loans to such day.

SECTION 8.03. Increased Cost and Reduced Return. (a) If any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Applicable Lending Office) or any Issuing Bank with any request or directive (whether or not having the force of law) of any such governmental authority, central bank or comparable agency, made or adopted after the date hereof (other than a change currently provided for in any existing law, rule or regulation) shall impose, modify or deem applicable any reserve, special deposit, insurance assessment or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding, with respect to any Euro-Dollar Loan, any such requirement with respect to which such Lender is entitled to compensation during the relevant Interest Period under Section 2.16) against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Applicable Lending Office) or any Issuing Bank or shall impose on any Lender (or its Applicable Lending Office) or any Issuing Bank or on the United States market for certificates of deposit or the London interbank market any other condition affecting its Fixed Rate Loans (other than Money Market Absolute Rate Loans), its Note (in respect of such Fixed Rate Loans), its obligation to make such Fixed Rate Loans or its participating in, issuing or maintaining any Letter of Credit; and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) or such Issuing Bank of making or maintaining any Fixed Rate Loan, participating in, issuing or maintaining any Letter of Credit, or to reduce the amount of any sum received or receivable by such Lender (or its Applicable Lending Office) or such Issuing Bank under this Agreement or under its Note with respect thereto, by an amount reasonably deemed by such Lender or such Issuing Bank to be material, then, within 15 days after demand by such Lender or such Issuing Bank (with a copy to the Agent), the Borrower shall pay to such Lender or such Issuing Bank such additional amount or amounts as will compensate such Lender or such Issuing Bank for such increased cost or reduction.

(b) If any Lender or any Issuing Bank shall have determined that any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank or comparable agency, made or adopted after the date hereof (other than a change currently provided for in any existing law, rule or regulation), has or would have the effect of increasing the amount of capital of such Lender or such Issuing Bank (or its parent) required to be maintained in respect of, or otherwise allocated to, such Lender or such Issuing Bank’s obligations hereunder (its “Required Capital”) by an amount reasonably deemed by such Lender or such Issuing Bank to be material, then such Lender or such Issuing Bank may, by notice to the Borrower and the Agent, increase the facility fee, letter of credit fee or fronting fee payable to such Lender or such Issuing Bank hereunder to the extent required so that the ratio of (w) the sum of the increased facility fee, letter of credit fee or fronting fee applicable to such Lender or such Issuing Bank’s Commitment or Loans hereunder to (x) the prior facility fee, letter of credit fee or fronting fee applicable to such Lender’s or such Issuing Bank’s Commitment or Loans or Letters of Credit (or participations therein) hereunder is the same as the ratio of (y) such Lender’s or such Issuing Bank’s increased Required Capital to (z) its prior Required Capital. Such Lender or such Issuing Bank’s notice to the Borrower and the Agent shall set forth its calculation of the foregoing ratios and the increased facility fee, letter of credit fee or fronting fee to which it is entitled under this Section.

(c) Each Lender or each Issuing Bank will promptly notify the Borrower and the Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender or such Issuing Bank to compensation pursuant to this Section 8.03 (each, a “Trigger Event”) and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender or such Issuing Bank, be otherwise disadvantageous to such Lender or such Issuing Bank. Notwithstanding any other provision of this Section 8.03, neither any Lender nor any Issuing Bank shall be entitled to any compensation pursuant to this Section 8.03 in respect of any Trigger Event (i) for any period of time in excess of 120 days prior to such notice or (ii) for any period of time prior to such notice if such Lender or such Issuing Bank (as applicable) shall not have given such notice within 120 days of the date on which such Trigger Event shall have been enacted, promulgated, adopted or issued in definitive or final form unless such Trigger Event is retroactive. A certificate of any Lender or any Issuing Bank claiming compensation under Section 8.03(a) or (b) and setting forth the additional amount or amounts to be paid to it hereunder and describing the method of calculation thereof shall be conclusive if made reasonably and in good faith. In determining such amount, such Lender or such Issuing Bank may use any reasonable averaging and attribution methods.

SECTION 8.04. Taxes. (a) For purposes of this Section 8.04, the following terms have the following meanings:

“Taxes” means any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings with respect to any payment by the Borrower pursuant to this Agreement or under any Note, and all liabilities with respect thereto, excluding (i) in the case of each Lender, each Issuing Bank and the Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by a jurisdiction under the laws of which such Lender, such Issuing Bank or the Agent (as the case may be) is organized or in which its principal executive office is located or, in the case of each Lender, in which its Applicable Lending Office is located and (ii) in the case of each Lender, any United States withholding tax imposed on such payments but only to the extent that such Lender is subject to United States withholding tax at the time such Lender first becomes a party to this Agreement.

“Other Taxes” means any present or future stamp or documentary taxes and any other excise or property taxes, or similar charges or levies, which arise from any payment made pursuant to this Agreement or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note.

(b) Any and all payments by the Borrower to or for the account of any Lender, any Issuing Bank or the Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if the Borrower shall be required by law to deduct any Taxes or Other Taxes from any such payments, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 8.04) such Lender, such Issuing Bank or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (iv) the Borrower shall furnish to the Agent, at its address referred to in Section 9.01, the original or a certified copy of a receipt evidencing payment thereof.

(c) The Borrower agrees to indemnify each Lender, each Issuing Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this Section 8.04) paid by such Lender, such Issuing Bank or the Agent (as the case may be) and any liability (including penalties, interest and expenses, except to the extent attributable to the negligence or misconduct of such Lender, such Issuing Bank or the Agent, as the case may be) arising therefrom or with respect thereto. This indemnification shall be made within 15 days from the date such Lender, such Issuing Bank or the Agent (as the case may be) makes demand therefor.

(d) Each Lender organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this Agreement in the case of each Lender listed on the signature pages hereof and on or prior to the date on which it becomes a Lender in the case of each other Lender, shall provide the Borrower with (i) two Internal Revenue Service (“IRS”) forms W8-BEN or any successor form prescribed by the IRS, certifying that such Lender is entitled to benefits under an income tax treaty to which the United States is a party which exempts such Lender from United States withholding tax or reduces the rate of withholding tax on payments of interest and eliminates withholding tax on any fees, or (ii) two IRS forms W8-ECI certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. If the form provided by a Lender indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from “Taxes” as defined in Section 8.04(a). Each such Lender undertakes to deliver to each of the Borrower and the Agent (A) a replacement form (or successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and (B) such amendments thereto or extensions or renewals thereof as may reasonably be required (but only so long as such Lender remains lawfully able to do so).

(e) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form pursuant to Section 8.04(d) (unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 8.04(b) or Section 8.04(c) with respect to Taxes imposed by the United States; provided that if a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such Taxes.

(f) Each Lender will promptly notify the Borrower and the Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to make any claim for indemnification in respect of Taxes or Other Taxes pursuant to this Section 8.04 (each, a “Tax Event”) and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such claim or any other amounts payable by the Borrower under this Section 8.04 and will not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. Notwithstanding any other provisions of this Section, no Lender shall be entitled to any indemnification pursuant to this Section in respect of any Tax Event (i) for any period of time in excess of 180 days prior to such notice or (ii) for any period of time prior to such notice if such Lender shall not have given such notice within 120 days of the date on which such Lender became aware of such Tax Event unless such Tax Event is retroactive.

SECTION 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Lender to make or maintain Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Lender has demanded compensation under Section 8.03(a) and the Borrower shall, by at least five Euro-Dollar Business Days prior notice to such Lender through the Agent, have elected that the provisions of this Section shall apply to such Lender, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply:

(a) all Loans which would otherwise be made by such Lender as (or continued as or converted into) Euro-Dollar Loans shall instead be Base Rate Loans, and (b) after each of its outstanding Euro-Dollar Loans has been repaid (or converted to a Base Rate Loan), all payments of principal which would otherwise be applied to repay such Euro-Dollar Loans shall be applied to repay its Base Rate Loans instead.

If such Lender notifies the Borrower that the circumstances giving rise to such notice no longer apply, the Borrower shall elect that the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Lenders.

SECTION 8.06. Substitution of Lender. If (i) the obligation of any Lender to make Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Lender has demanded compensation under Section 8.03 or 8.04 or (iii) any Lender shall be a Declining Lender pursuant to Section 2.06(c), the Borrower shall have the right to seek a substitute financial institution or financial institutions (“Substitute Lenders”) (which may be one or more of the Lenders) to purchase the Loans and assume the Commitment of such Lender (the “Affected Lender”) under this Agreement and, if the Borrower locates a Substitute Lender, the Affected Lender shall, upon payment to it of the purchase price agreed between it and the Substitute Lender (or, failing such agreement, a purchase price in the amount of the outstanding principal amount of its Loans and accrued interest thereon to the date of payment) plus any amount (other than principal and interest) then due to it or accrued for its account hereunder, assign all its rights and obligations under this Agreement and all of its Notes to the Substitute Lender, and the Substitute Lender shall assume such rights and obligations, whereupon the Substitute Lender shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender.

SECTION 8.07. Election to Terminate. If during any Level I Period, Level II Period, Level III Period, Level IV Period or Level V Period (i) the obligation of any Lender to make Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Lender has demanded compensation under Section 8.03 or 8.04, the Borrower may elect to terminate this Agreement as to such Lender, and in connection therewith not to borrow any Loan hereunder from such Lender or to prepay any Base Rate Loan made pursuant to Section 8.02 or 8.05 (without altering the Commitments or Loans of the remaining Lenders); provided that the Borrower (i) notifies such Lender through the Agent of such election at least two Euro-Dollar Business Days before any date fixed for such borrowing or such a prepayment, as the case may be, and (ii) repays all of such Lender’s outstanding Loans, accrued interest thereon and any other amounts then due to such Lender or accrued for its account hereunder concurrently with such termination. Upon receipt by the Agent of such notice, the Commitment of such Lender shall terminate.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses of the Agent, including reasonable fees and disbursements of special counsel for the Agent, in connection with the preparation and administration of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder, (ii) if an Event of Default occurs, all out-of-pocket expenses incurred by the Agent or any Lender or any Issuing Bank, including fees and disbursements of counsel, in connection with such Event of Default and collection and other enforcement proceedings resulting therefrom, and (iii) all reasonable out-of-pocket expenses incurred by any Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder.

(b) The Borrower agrees to indemnify the Agent, each Lender and each Issuing Bank and each of their respective Affiliates, and the directors, officers, employees, agents and advisors of each of the foregoing (each, an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, claims, losses, damages, penalties, costs and expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by any Indemnitee relating to or arising out of (i) the execution or delivery of this Agreement or the performance of the parties hereto of their respective obligations hereunder, (ii) any actual or proposed use of proceeds of Loans hereunder, (iii) any actual or proposed use of any Letter of Credit issued pursuant to this Agreement (including any refusal by any Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit) or (iv) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that no Indemnitee shall have the right to be indemnified hereunder for its own gross negligence or willful misconduct as determined by a court of competent jurisdiction. To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any Loan or Letter of Credit or the use of proceeds thereof.

(c) The agreements in this Section 9.03 shall survive the termination of the Commitments and this Agreement, and the repayment, satisfaction or discharge of the Loans and all the other amounts due hereunder.

SECTION 9.04. Amendments and Waivers. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Agent are affected thereby, by the Agent); provided that no such amendment or waiver shall, unless signed by each Lender directly affected thereby, (i) increase or, other than pursuant to Section 2.06(c), decrease the Commitment of any Lender or subject any Lender to any additional obligation, (ii) reduce or forgive the principal of or rate of interest on any Loan or LC Disbursement or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any Loan or LC Disbursement or any fees hereunder or for any reduction or termination of any Commitment or (iv) change Section 2.07(c) or Section 2.13(c) or any other provision requiring the ratable sharing of payments or reduction of Commitments among the Lenders; provided further that no such amendment or waiver shall (i) unless signed by all the Lenders, amend this Section 9.04 or otherwise change the percentage of the Commitments or of the aggregate unpaid principal amount of the Loans or LC Exposure, or the number of Lenders, which shall be required for the Lenders or any of them to take any action under this Section 9.04 or any other provision of this Agreement; or (ii) amend, modify or otherwise affect the rights or duties of Issuing Banks without the prior written consent of each Issuing Bank.

SECTION 9.05. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit), except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender and each Issuing Bank (and any attempted assignment or transfer by the Borrower without such consent shall be null and void), except as contemplated by Section 5.05. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit) and each Indemnitee) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) each of the Agent, each Issuing Bank and, except in the case of an assignment to a Lender or an Affiliate of a Lender, the Borrower must give their prior written consent to such assignment (which consents shall not be unreasonably withheld, it being understood that it shall be reasonable for the Borrower to withhold consent if the proposed assignee does not have an investment grade rating), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment (or, if the Commitments have terminated, the entire amount of its outstanding Loans and LC Exposure), the amount of the Commitment (or, if the Commitments have terminated, the amount of the outstanding Loans and LC Exposure) of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Agent) shall not be less than $5,000,000 unless each of the Borrower and the Agent otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, except that this clause (iii) shall not apply to rights in respect of outstanding Money Market Loans, (iv) the parties to each assignment shall execute and deliver to the Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 (except that such fee shall not be payable in the case of an assignment by a Lender to one of its Affiliates or to another Lender), and (v) the assignee, if it shall not be a Lender, shall deliver to the Agent an Administrative Questionnaire; and provided further that any consent of the Borrower otherwise required under this Section 9.05(b) shall not be required if an Event of Default under Section 6.01(a), Section 6.01(b), Section 6.01(g) or Section 6.01(h) has occurred and is continuing. Subject to acceptance and recording thereof pursuant to Section 9.05(d), from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14, 8.03, 8.05 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.05(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 9.05(e).

(c) The Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to and LC Exposure of, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, any Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 9.05(b) and any written consent to such assignment required by Section 9.05(b), the Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 9.05(d).

(e) Any Lender may, without the consent of the Borrower, the Issuing Banks or the Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Agent, the Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.04 that affects such Participant. Subject to Section 9.05(f), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.14, 2.16, 8.03 and 8.04 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.05(b).

(f) A Participant shall not be entitled to receive any greater payment under Section 8.03 or 8.04 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent or by reason of the provisions of Section 8.02, 8.03 or 8.04 requiring such Lender to designate a different Applicable Lending Office under certain circumstances.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.06. USA Patriot Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the requirements of the USA Patriot Act. The Borrower hereby agrees to cooperate with each Lender to provide such information promptly following a request therefor from such Lender.

SECTION 9.07. Governing Law; Jurisdiction; Consent to Service of Process. (a)This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees, to the fullest extent permitted by law, that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right any party hereto may otherwise have to bring any action or proceeding relating to this Agreement against any other party hereto or its properties in the courts of any jurisdiction.

(c) Each of the parties hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in Section 9.07(b). Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each of the parties hereto hereby irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.08. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by facsimile transmission or other electronic transmission shall be as effective as delivery of a manually executed counterpart of this Agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof.

SECTION 9.11. Confidentiality. Each Lender agrees to maintain and to cause its Affiliates to maintain the confidentiality of all non-public information provided to it by the Borrower or any Subsidiary, or by the Agent on the Borrower’s or such Subsidiary’s behalf, under this Agreement, and neither it nor any of its Affiliates shall use any such information other than in connection with or in enforcement of this Agreement or in connection with other business now or hereafter existing or contemplated with the Borrower or any Subsidiary; except to the extent such information (i) was or becomes generally available to the public other than as a result of disclosure by such Lender or its Affiliates or their respective directors, officers, employees and agents, or (ii) was or becomes available on a non-confidential basis from a source other than the Borrower or any of its Subsidiaries so long as such source is not, to the knowledge of such Lender, prohibited from disclosing such information by a legal, contractual or fiduciary obligation to the Borrower or any of its Affiliates; provided, however, that any Lender may disclose such information (A) at the request or pursuant to any requirement of any self-regulatory body, governmental body, agency or official to which such Lender or any of its Affiliates is subject or in connection with an examination of such Lender or Affiliate thereof by any such authority or body; (B) pursuant to subpoena or other court process; (C) when require to do so in accordance with the provisions of any applicable requirement of law; (D) to the extent reasonably required in connection with any litigation or proceeding to which the Agent, any Lender or their respective Affiliates may be party; (E) to the extent reasonably required in connection with the exercise of any remedy hereunder; (F) to such Lender’s independent auditors, counsel, and any other professional advisors of such Lender who are advised of the confidentiality of such information; (G) to any Participant or assignee, actual or potential, provided that such Person agrees to keep such information confidential to the same extent required of the Lenders hereunder; (H) as to any Lender or its Affiliate, as expressly permitted under the terms of any other document or agreement regarding confidentiality to which the Borrower or any Subsidiary is party with such Lender or such Affiliate; (I) to its Affiliates and its and its Affiliates’ directors, officers, employees and agents, provided that each such Affiliate, director, officer, employee or agent shall keep such information confidential to the same extent required of the Lenders hereunder; and (J) to any other party to the Agreement. Each Lender shall be responsible for any breach of this Section 9.11 by any of its Affiliates or any of its or its Affiliates’ directors, officers, employees and agents.
